Devon Tower: From Brown to Gold Larry Nichols May 23, 2012 Site Selection 1
Previous site uses Several automobile fueling and service operations were established and operated for numerous years Operations ceased when the Terminal Building for mass transit was erected circa 1910 Terminal Building was the hub of the trolley system for Oklahoma City Outlying community mass transit also housed within Terminal Building 2

Previous site uses, cont. Site was converted to a motor hotel in late 1920s or early 1930s The motor hotel provided services for automobiles The building was demolished in the 1950s Construction began shortly after on a four-story parking deck The parking deck area provided automotive fueling and maintenance services until the early 1970s 4
Brownfield Site 5
Demolition 100 percent of the material product from the parking deck demolition was diverted from landfill 11,200 tons of concrete were recycled and used for erosion control on a lake-front property More than 15,200 tons were processed to be used as ODOT coarse rock Nearly 500 tons of metal were removed from the existing buildings and sent to recycling facilities for miscellaneous use About 500 working light fixtures were removed and sent to OESCO s warehouse for re-use 6

LEED Certification LEED projects in Oklahoma LEED certified buildings in Oklahoma* 36 LEED certified 12 certified LEED Gold (nine are government buildings) When complete, the building is expected to receive LEED Gold recognition. Sustainable Site 8 points Water Efficiency 3 points Energy and Atmosphere 5 points Materials and Resources 7 points Indoor Environmental Quality 13 points Innovation and Design 5 points The project will not be certified until it is complete and the final scorecard has been submitted to the U.S. Green Buildings Council * Source: Latest available data from U.S. Green Building Council 13
LEED credits, site and space Site selected for construction was a Brownfield Site was not environmentally sensitive Site provides connection with surrounding community About 20 percent of site provides public open space More than 80,000 square feet of vegetated areas and at-grade hardscapes Bicycle racks, on-site showers and easy access to public transportation provide commuter-friendly workplace LEED credits, construction waste To date, 93 percent of the construction waste has been recycled. The following materials were sent to recycling facilities: 62,565 tons of concrete 2,485 tons of wood 2,484 tons of metal 1,486 tons of gypsum 6 tons of plastics = 69,026 tons of recycled construction materials 14
LEED credits, energy performance District cooling and state-of-the-art energy management technologies maximize efficiency Tower geometry and exterior glass fins reduce solar load Energy efficient light fixtures use minimal energy to operate Light fixtures dim automatically based on available natural light Occupancy sensors dim lights when space is not occupied Raised floor air distribution increases air flow efficiency LEED credits, water and heat Total water conservation calculated at about 42 percent Reduced landscape irrigation needs by 50 percent Low-flow lavatories and automatic wash basin fixtures Covered parking mitigates harmful heat Vegetated and/or light-colored roofs mitigate effects of heat 15
Above and beyond LEED Tower s geometry and glass walls provide abundant natural light for employees in all areas of tower 60 percent of wood used for interior finishes came from sustainable forests Revitalizing downtown: Project 180 A Tax Increment Financing District (TIF) was established using funds from the Devon construction project Proceeds used for downtown improvements and future economic development The improvement project, known as Project 180, is led by the City of Oklahoma City The project includes improved downtown streetscapes, sidewalks, parks and public spaces Myriad Botanical Gardens received full makeover 16
